Question

当我尝试使用Maven编译时，我收到此错误：

INFO: HHH000041: Configured SessionFactory: null
Error creating Session: org.hibernate.InvalidMappingException: Could not parse mapping document from resource com/baskeitor/models/User.hbm.xml

但我不知道错误在哪里：

User.java

package main.java.com.project.models;

public class User实现java.io.Serializable {

private static final long serialVersionUID = 1L;

private Long id;

private String firstName;
private String secondName;
private String email;
private String password;
private Set<Artifact> artifact = new HashSet<Artifact>();

public User(){}

public User(String firstName, String secondName, String email, String password){
    this.firstName = firstName;
    this.secondName = secondName;
    this.email = email;
    this.password = password;
}   

public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}

public Set<Artifact> getArtifacts() {
    return teams;
}

public void setArtifacts(Set<Artifact> artifacts) {
    this.teams = team;
}

public String getFirstName() {
    return firstName;
}

public void setFirstName(String firstName) {
    this.firstName = firstName;
}

public String getSecondName() {
    return secondName;
}

public void setSecondName(String secondName) {
    this.secondName = secondName;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

}

User.hbm.xml

当maven运行测试时我收到此错误，我尝试获取HibernateUtil.getSessionFactory（）;

这里似乎存在一些问题，首先，无法找到hibernate映射文件。特别的是，你在maven输出中给出的位置与你在hibernate配置中指定的位置不匹配。

你有

<mapping resource="com/project/models/User.hbm.xml"/>

但是hibernate抱怨无法找到com/baskeitor/models/User.hbm.xml。这个值显然是由hibernate任意组成的，所以它必须设置在某个地方。尝试使用您喜欢的文件搜索并搜索文件。

此外，hibernate-mapping元素的package属性存在问题，在hbm文件中设置为com.project.models但实际包为main.java.com.project.models。

因此，由于您在hibernate-mapping元素中指定的包名称在映射文档中的非限定类名前面加前缀，因此类元素中的类名将为com.project.models.User，它不会t匹配实际的类名。

（在侧节点上，为什么不使用注释？他们觉得使用imho更自然）
